Returning to Canada

Returning resets your tax residency — but the basis adjustment on departure-taxed assets, foreign retirement account treatment, and TFSA room gap create planning opportunities and traps.

TaxKiln framework

Five-Stage Emigration Tax Lifecycle

TaxKiln's lifecycle framework for Canadian emigration tax: (1) pre-departure planning — asset reorganisation, CDA extraction, LCGE crystallisation, RRSP/TFSA timing, provincial residency strategy; (2) departure tax crystallisation — s.128.1(4) deemed disposition, T1243/T1161, T1244 security; (3) treaty positioning — Article IV tie-breaker, destination pension/RRSP treatment, withholding reduction; (4) post-departure compliance — Section 116 on TCP, Part XIII on passive income, provincial trailing tax; (5) return — s.128.1(7) basis reset, foreign retirement account elections, TFSA/RRSP room recalculation.

1. Residency resumption

Residency restarts when significant ties are re-established (home, spouse/partner, dependants). The year of return is a part-year resident return: worldwide income only from the date of return, foreign-source income before the return date not taxed in Canada.

2. Basis reset — s. 128.1(7)

On becoming Canadian-resident again, ITA s. 128.1(7) deems property reacquired at FMV on the return date, creating a step-up in basis. For assets that were subject to deemed disposition under s. 128.1(4) on the original departure (and tax paid), this means the historic appreciation has already been taxed once — only post-return appreciation is now Canadian-taxable. Election under s. 128.1(6) is available to unwind the departure-tax deemed disposition on property still owned at return — restoring original ACB and refunding the departure tax — useful where the asset has fallen below departure FMV.

3. Foreign retirement accounts

US 401(k) and Traditional IRA

Treaty Article XVIII(7) grants a one-time election to defer Canadian tax on the accrued (but undistributed) earnings of a US-source pension or retirement arrangement. File on the first Canadian return after becoming resident. Internal growth remains tax-deferred until distribution; Canada then taxes the distribution with foreign tax credit for any US tax withheld.

Roth IRA

The Roth is recognised as a pension under Article XVIII. To preserve tax-free status in Canada, file a one-time Roth IRA election with CRA (Article XVIII(7) plus CRA notification) in the year of return. Do not contribute to a Roth after becoming a Canadian resident — Canadian contributions taint the wrapper and growth attributable to them becomes taxable.

UK SIPP / occupational pension

UK pensions are recognised under the Canada–UK treaty Article XVII. Lump-sum vs periodic taxation differs; the UK 25% pension commencement lump sum is not automatically tax-free in Canada.

s. 60(j) lump-sum rollover

ITA s. 60(j) permits a tax-deferred rollover into an RRSP of a lump-sum receipt from a foreign pension plan attributable to services rendered while non-resident, within prescribed limits.

4. TFSA — the room gap

TFSA room does not accumulate during years of non-residency. Pre-departure room is preserved and can be used after return. Contributions made while non-resident attract a 1%/month over-contribution penalty until withdrawal — review and clean up before re-entry.

5. RRSP — pre-departure room preserved

RRSP contribution room earned before departure remains intact, and new room accrues from Canadian earned income post-return. Note the prior-year earned-income calculation: contribution room for the year of return is based on the previous year's Canadian earned income (which may be zero), so significant new room may not appear until the second year back.

6. Re-entry checklist

Reapply for provincial healthcare (most provinces 3-month wait).
Update SIN / banking / brokerage to Canadian-resident status.
File s. 128.1(6) unwind election if departure-tax assets fell below FMV.
File Article XVIII(7) election for US/UK pension accounts on first return.
Withdraw any non-resident TFSA contributions before re-entry to stop 1%/month penalty.
Reapply for CCB (RC66) and GST/HST credit (RC151) — not automatic.
Confirm CCPC residence: returning shareholders may bring central management and control back to Canada.

Worked example — returning after 10 years in UAE

Persona: Anya, age 50, returning to Ontario after 10 years in Dubai. Holds a UAE investment portfolio (CAD $1.4M) and a 401(k) accumulated during a prior US assignment ($220k). On return, s. 128.1(7) deems portfolio reacquired at FMV — only future Canadian-resident appreciation will be taxed. She files an Article XVIII(7) one-time election preserving 401(k) deferral. Her TFSA room held intact from pre-2014 departure plus pre-departure unused room totals ≈ $46k available to contribute immediately. Reapplies for OHIP (90-day wait) and registers business (HST when >$30k).
